I’ve setup raspberry pi to connect to 4G and connect pixhawk to Mission Planner over 4G. It works flawlessly when I power the raspberry pi 4 to outlet, and power the pixhawk with a battery. I’m able to connect to Mission Planner with TCP or UDP. However, I connected the battery to 2 BECs. 1 powers the pixhawk and 1 powers raspberry pi (RPI). RPI connects to internet, I’m able to access the ardupilot website (RPI’s IP address). In system info, Baudrate shows: Not in use, Mavlink count shows numbers, but I cannot connect to Mission Planner or QGC. I’m able to stream the video from RPI, but I cannot connect to Mission Planner. Please let know if anyone has any idea why it’s happening.
